Accurate prediction of intra-protein residue contacts from sequence information will allow the prediction of protein structures. Basic predictions of such specific contacts can be further refined by jointly analyzing predicted contacts, and by adding information on the relative positions of contacts in the protein primary sequence. We introduce a method for(More)
Studies of children’s causal learning typically provide learners with clear evidence for direct causal relations, e.g., a machine that activates when a toy is placed upon it. But causal systems in the real world often present indirect perceptual evidence generated by interactions between hidden variables: Consider a child trying to figure out what’s inside(More)
Many beliefs about oneself are constructed through experiences, but the kinds of evidence that inform these beliefs in early childhood are not well understood. One critical source of information that affects adults and older children’s appraisals of their abilities and traits is social comparison. We found that even fourand five-year-olds (mean=56 months)(More)
By the age of 5, children explicitly represent that agents can have both true and false beliefs based on epistemic access to information (e.g., Wellman, Cross, & Watson, 2001). Children also begin to understand that agents can view identical evidence and draw different inferences from it (e.g., Carpendale & Chandler, 1996). However, much less is known about(More)
Even infants expect agents to act rationally in pursuit of their goals. However, little research has looked at whether young children expect other agents to learn rationally. In the current study, we investigated 4.5to 6-year-olds’ reasoning about another agent’s beliefs after the agent observed a sample drawn randomly or selectively from a population. We(More)
We discuss a process by which non-moral concerns (that is concerns agreed to be non-moral within a particular cultural context) can take on moral content. We refer to this phenomenon as moral alchemy and suggest that it arises because moral obligations of care entail recursively valuing loved ones' values, thus allowing propositions with no moral weight in(More)
Quantifier Raising (QR) is an instance of covert movement – movement which has been argued to lack an explicit cue for children to acquire. Significant attention has been given to the acquisition of QR in the literature, and many studies of the acquisition of QR have investigated children’s ability to interpret sentences where different scope relations are(More)
In cooperative activities, all parties have a shared goal but may not have the same set of skills. The current study considers whether preschoolers are sensitive to probable differences in individuals’ competence when allocating roles. We found that 3.5to 5.5-year-olds use relative competence, as indexed by the age of their intended partner, to determine(More)
Iconicity is prevalent in gesture and in sign languages, yet the degree to which children recognize and leverage iconicity for early language learning is unclear. In Experiment 1 of the current study, we presented sign-naïve 3-, 4- and 5-year-olds (n=87) with iconic shape gestures and no additional scaffolding to ask whether children can spontaneously map(More)
